Cloudfare Captcha

Since the installation of a new PC (a couple of months now) running Ubuntu 24.04/Linux, addressing the domoticz site (forum or wiki) results in Cloudfare asking for a Captcha "Verifying you are human by completing the action below ... forum.domoticz.com needs to review the security of your connection before proceeding".
Is there any configuration at the domoticz website that triggers this (annoying) behavior?
Any action that can be done to avoid?

Hi,

It is pure coincidence that your installation of a new PC with a new Linux OS happens at about the same time that it appears to be necessary to protect the Domoticz forum site against DDOS attacks

So there is nothing that you or others can do to avoid that way of protection. Unfortunately it is needed.

B.t.w. you should not publish your IP address, as this will attract attackers.

Regards

The /13 subnet range is quite a big number of ip addresses that are covered by that. ;)

There’s no way to bypass it permanently, but you could try using a different browser, enabling JavaScript fully, or even a VPN to see if that helps reduce how often you get the challenge ;)
So you registered on our forums just to echo what was already stated or are there other intentions here?
